<textarea> and ajax with serialize()...HELP

I'm using ajax to process a form. But my form has textareas in them. Its not passing the textarea values.
Here is my javascript code:

  1.  $.get( 
                 "process_order.php", 
                 $("#order").serialize(), 
                 function(data){
                 $('#loader').hide();
                    if(data) {
                     pTag = "<img src='http://www.heartofgold-usa.com/images/saved.png' width='200px'><br />Order Saved";
                     $('#popup').empty();
                     jQuery("#popup").append(pTag);
                     jQuery("#popup").dialog('open');
                     } else {
                     pTag = "<img src='http://www.heartofgold-usa.com/images/error.png' width='200px'><br />There was an error!<br /><font size='1px'>" + data + "</font>";
                     $('#popup').empty();
                     jQuery("#popup").append(pTag);
                     jQuery("#popup").dialog('open');
                     }
                     
                    },
                "html"
                );


















I just have a simple textarea section and I NEED to allow HTML code in that text area.
